Description

Technical Field

[0001] The invention belongs to the technical field of boiler water level control, and in particular relates to an intelligent boiler water level control device. Background Art

[0002] A boiler is a heat energy conversion device that converts chemical energy, electrical energy, etc. into thermal energy by burning fuel (such as coal, natural gas, biomass, etc.) or utilizing other energy (such as electricity, waste heat), and outputs steam, high-temperature water or organic heat carriers. The heat energy released by the fuel combustion is efficiently transferred to the working fluid (water or other fluid) in the "pot" through the "furnace" part of the boiler, realizing heat energy storage and transfer, heating the working fluid to a specific temperature and pressure, and meeting the differentiated heat energy needs of different scenarios. Boilers are widely used in industrial, civil and commercial fields;

[0003] At present, there are strict requirements for water bodies during the operation of boilers. If the water level in the boiler is too high, it will compress the steam space in the drum, reduce the steam-water separation efficiency, and cause steam to carry boiler water. When the water level is lower than the visible range, the water-cooled wall tubes and downcomers are directly exposed to high temperature positions, and the material strength drops rapidly, which may cause the tube wall to burn or burst. The existing technology requires the installation of a variety of high-tech intelligent products on the boiler to conduct real-time detection of the boiler water level. The operating cost is too high, and subsequent maintenance and replacement also require a lot of money. Summary of the Invention

[0006] The two alarm structures each have a T-shaped slide that is slidably connected to the inner walls of the two T-shaped slots. The other ends of the two T-shaped slides are fixedly connected to an empty slot plate, and a connecting rope is fixedly connected between the two empty slot plates.

[0007] Preferably, the two alarm structures also include two groups of elastic telescopic parts fixedly connected to the upper and lower outer walls of the hollow slot plate, and the other end of each group of elastic telescopic parts is jointly and fixedly connected to a buoyant water board, and the surface of each buoyant water board is provided with a waterproof layer.

[0008] Preferably, the inner walls of the two buoyant water plates are fixedly connected with bellows, the upper and lower ends of the hollow slot plate are provided with air grooves, the other ends of the two bellows are fixedly connected to the upper and lower outer walls of the hollow slot plate, and the inner wall of each air groove is fixedly connected with a special-shaped air pipe.

[0009] Preferably, a hollow whistle body is fixedly connected to the other pipe opening of the two special-shaped tracheas, a reed is fixedly connected to the opposite pipe opening of the two hollow whistle bodies, and a trapezoidal air groove is provided on the end of the pipe body of the two hollow whistle bodies close to the reed, and the other ends of the two hollow whistle bodies are respectively fixedly connected to the upper and lower inner walls of the hollow slot plate.

[0010] Preferably, an L-shaped plate frame is fixedly connected to the outer wall of one end of the hollow slot plate, and a triangular plate is fixedly connected to the plate body of the other end of the L-shaped plate frame. A plate rod is intermittently slidably connected to the outer wall of one end of the inclined surface of the triangular plate.

[0011] Preferably, an L-shaped ball rod is fixedly connected to the rod body at one end of the plate rod, and a rectangular groove that can be fitted and slidably connected to a section of the plate body of the plate rod is opened in the inner wall of the bottom end of the boiler body.

[0012] Preferably, a spring is fixedly connected to the plate body at one end of the bottom of the plate rod, and the other end of the spring is fixedly connected to the inner wall of the other end of the rectangular groove.

[0013] Preferably, each of the water supply pipes has an arc-angle baffle plate fitted and rotatably connected to the inner wall of the tube body on one side, and the arc-angle baffle plate is specifically made of natural rubber material at the arc angle part, and the other end of the L-shaped ball rod can be fitted and connected to the side wall of one end of the arc-angle baffle plate.

[0014] Preferably, a vertical shaft is fixedly connected through the center of the arc angle baffle, and the vertical shaft is rotatably connected to the upper and lower ends of the water supply pipe.

That is, the sound emitted by the hollow sentinel body can be used to alert the staff to pay attention to the boiler water level gauge and make corresponding work decisions such as shutting down the water pump to store water.

[0018] In the process of the present invention contacting a group of water level plates below through the buoyancy water plate, the triangular plate installed on the outer wall of the empty slot plate will first contact the top of the plate rod, and as the triangular plate gradually moves downward, it drives the plate rod to move according to the inclined surface of one end of the triangular plate, thereby squeezing the spring in the rectangular slot, and the translation of the plate rod will drive the L-shaped ball rod to translate in real time, thereby touching the side wall of the arc-angle baffle, so that it is forced to rotate on the water supply pipe together with the vertical axis. The rotation of the vertical axis will drive the torsion spring in the cylindrical slot to wrap and deform, and the arc-angle baffle driven to tilt 90 degrees can facilitate the operation of water storage in the boiler body. The staff only needs to hear the sound made by the buoyancy water plate contacting the water level plate, notice the boiler water level gauge, and start the water pump in the existing technical device to store water. Therefore, the operating cost is greatly reduced, and subsequent maintenance is convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example 1

[0031] like Figures 1 to 7 As shown, the present invention provides an intelligent boiler water level control device, including a boiler body 1, with water supply pipes 11 fixedly connected to both ends of the boiler body 1 near the bottom, a boiler water level gauge fixedly connected to the outer wall of one end of the boiler body 1, a water level control unit 2 is provided in the boiler body 1, and the water level control unit 2 includes two sets of water level plates 21 fixedly connected to the inner walls of both ends of the boiler body 1, and T-shaped chutes 22 are also opened in the inner walls of both ends of the boiler body 1, and alarm structures are provided in the two T-shaped chutes 22. A gate opening structure is jointly provided between the two water supply pipes 11 and the inner wall of the boiler body 1;

[0032] Both alarm structures have T-shaped slides 23 that are slidably connected to the inner walls of the two T-shaped slides 22. The other ends of the two T-shaped slides 23 are fixedly connected to empty slot plates 24, and a connecting rope 25 is fixedly connected between the two empty slot plates 24.

[0033] The above scheme is adopted: the water in the boiler body 1 is used to drive the empty slot plate 24 to move up and down. When the empty slot plate 24 is passively moved, it will slide within the T-shaped slide 22 through the connected T-shaped slide plate 23. Therefore, when the empty slot plate 24 moves and drives the buoyant water plate 27 to contact the water level plate 21, the fluctuation of the water body and the rise of the water body will cause the buoyant water plate 27 to be forced to squeeze the bellows 28, so that extruded gas is generated inside. Then, the gas generated in the bellows 28 will enter the hollow sentinel body 230 through the special-shaped air pipe 29, and encounter the trapezoidal air groove 232 provided on the hollow sentinel body 230. The 45-degree slope at one end of the trapezoidal air groove 232 will divide the airflow into two streams, thereby generating a sound. Instantly, the sound emitted by the hollow sentinel body 230 can be used to warn the staff;

[0034] When the water in the boiler body 1 gradually decreases, causing the buoyancy water plate 27 to contact a group of water level plates 21 below, the triangular plate 234 installed on the outer wall of the hollow plate 24 will first contact the top of the plate rod 235, and as the triangular plate 234 gradually moves downward, it drives the plate rod 235 to move according to the inclined surface of one end of the triangular plate 234. The translation of the plate rod 235 will drive the L-shaped ball rod 236 to translate in real time, thereby touching the side wall of the arc angle baffle 239, causing it to be forced to rotate together with the vertical axis 240 on the water supply pipe 11. The arc angle baffle 239 driven to tilt 90 degrees can facilitate the operation of water storage in the boiler body 1. The staff only needs to hear the sound made by the buoyancy water plate 27 contacting the water level plate 21, notice the boiler water level gauge, and start the water pump in the existing technical device to store water.

[0035] The two alarm structures also include two sets of elastic expansion members 26 fixedly connected to the outer walls of the upper and lower ends of the hollow slot plate 24. The other end of each set of elastic expansion members 26 is fixedly connected to a buoyant water plate 27. The surface of each buoyant water plate 27 is provided with a waterproof layer. The inner walls of the two buoyant water plates 27 are fixedly connected with a bellows 28. The upper and lower ends of the hollow slot plate 24 are provided with air grooves. The other ends of the two bellows 28 are connected to the upper and lower ends of the hollow slot plate 24. The outer walls at both ends are fixedly connected, and a special-shaped air tube 29 is fixedly connected to the inner wall of each air groove. A hollow sentinel body 230 is fixedly connected to the other pipe mouth of the two special-shaped air tubes 29, and a reed 231 is fixedly connected to the opposite pipe mouths of the two hollow sentinel bodies 230. A trapezoidal air groove 232 is provided on the end of the tube body of the two hollow sentinel bodies 230 close to the reed 231, and the other ends of the two hollow sentinel bodies 230 are respectively fixedly connected to the upper and lower inner walls of the hollow slot plate 24.

[0036] With the above solution, when the hollow slot plate 24 moves and drives the buoyant water plate 27 to contact the water level plate 21, the fluctuation of the water body and the rise of the water body will cause the buoyant water plate 27 to be forced to squeeze the bellows 28, causing extruded gas to be generated inside. At the same time, the elastic telescopic member 26 installed between the buoyant water plate 27 and the hollow slot plate 24 will also be forced to retract the rod body, and then the gas generated in the bellows 28 will enter the hollow sentinel body 230 through the special-shaped air pipe 29. When the airflow enters the cavity from the gap between the hollow sentinel body 230 and the reed 231, it encounters the trapezoidal air groove 232 opened on the hollow sentinel body 230. The 45-degree slope at one end of the trapezoidal air groove 232 will split the airflow into two streams, thereby generating a sound. The gas entering the cavity of the hollow sentinel body 230 will produce an amplified sound effect through the vibration of the air. In other words, the sound emitted by the hollow sentinel body 230 can be used to alert the staff to pay attention to the boiler water level gauge and make corresponding work decisions such as shutting down the water pump to store water.

[0037] An L-shaped plate frame 233 is fixedly connected to the outer wall of one end of the hollow slot plate 24, and a triangular plate 234 is fixedly connected to the plate body of the other end of the L-shaped plate frame 233. A plate rod 235 is intermittently connected to the outer wall of the inclined surface of the triangular plate 234 so as to fit and slide. An L-shaped ball rod 236 is fixedly connected to the rod body of one end of the plate rod 235. A rectangular groove 237 is provided in the inner wall of the bottom end of the boiler body 1 so as to fit and slide with a section of the plate body of the plate rod 235. A spring 238 is fixedly connected to the plate body of one end of the bottom of the plate rod 235, and the other end of the spring 238 is fixedly connected to the inner wall of the other end of the rectangular groove 237.

[0038] An arc-angle baffle 239 is respectively fitted and rotatably connected to the inner wall of the tube body on one side of each water supply pipe 11. The arc-angle baffle 239 is the arc-angle part and is specifically made of natural rubber material. The other end of the L-shaped ball rod 236 can be fitted and connected to the side wall of one end of the arc-angle baffle 239. A vertical shaft 240 is fixedly connected to the center position of the arc-angle baffle 239. The vertical shaft 240 and the upper and lower end tube bodies of the water supply pipe 11 are rotatably connected. A cylindrical groove 241 is provided in the inner wall of the furnace body of the boiler body 1, which can be movably connected to the shaft bodies at both ends of the vertical shaft 240. A torsion spring 242 is fixedly connected between the inner wall of one end of the two cylindrical grooves 241 and the upper and lower outer walls of the vertical shaft 240 respectively.

[0039] The above scheme is adopted: when the buoyant water plate 27 contacts the water level plate 21 below, the triangular plate 234 installed on the outer wall of the empty slot plate 24 will first contact the top of the plate rod 235, and as the triangular plate 234 gradually moves downward, it drives the plate rod 235 to move according to the inclined surface of one end of the triangular plate 234, thereby squeezing the spring 238 in the rectangular slot 237 to cause it to deform. The installation of the spring 238 is convenient for the subsequent triangular plate 234 to gradually separate from the plate rod 235, driving the plate rod 235 to reset. At the same time, the translation of the plate rod 235 will drive the L-shaped ball rod 236 to translate in real time, thereby touching the side wall of the arc angle baffle 239, causing it to be forced to rotate together with the vertical shaft 240 on the water supply pipe 11, and the rotation of the vertical shaft 240 will drive the cylindrical groove 241 The torsion spring 242 inside is wound and deformed, and the function of the torsion spring 242 is also to synchronously drive the arc-angle baffle 239 to reset again to seal the inner wall of the water supply pipe 11 when the L-shaped ball rod 236 is reset later. The arc-angle baffle 239 driven to tilt 90 degrees can facilitate the operation of water storage in the boiler body 1. The staff only needs to hear the sound made by the buoyancy water plate 27 contacting the water level plate 21, notice the boiler water level gauge, and start the water pump in the existing technical device to store water. In this way, the above-mentioned method can achieve early warning of the water level situation in the boiler body 1 to avoid damage, and automatically open the arc-angle baffle 239 acting as a water pipe valve, so that the boiler body 1 maintains the intelligent operation means while greatly reducing the operating cost, which is convenient for subsequent maintenance.

[0040] Example 2

[0041] Sensor system:

[0042] Electrode-type water level sensors, capacitive / differential pressure water level gauges, and multi-stage water level detection are set up; electrical signals are generated by electrodes contacting the water level to provide real-time feedback on the water level; water levels are converted through capacitance changes or pressure differences to support continuous monitoring of all working conditions; four-stage electrodes of ultra-high, high, low, and ultra-low are set up, corresponding to alarm, pump start-stop, interlock protection and other functions respectively, covering the complete safety range.

[0043] Control algorithm:

[0044] Set the three parameters of comprehensive water level, steam flow and feed water flow, and dynamically adjust the feed water valve through PID algorithm. When the steam load suddenly increases, the steam flow change is compensated first to avoid misjudgment caused by drum pressure fluctuation. Use PLC or dedicated microprocessor such as Siemens S7-200 to achieve: multi-period programming control (time-sharing start and stop of heating group), variable frequency speed regulation: automatically switch the water pump high-speed / low-speed operation according to water consumption, saving energy and reducing consumption.

[0045] Actuator:

[0046] Electric regulating valve: Receives the 4-20mA signal output by the controller and continuously adjusts the opening (non-traditional start-stop method) to achieve fine flow control; variable frequency water pump system: Adjusts the water pump speed through the inverter to match the actual water demand, reducing water hammer effect and mechanical wear.

[0047] Security protection mechanism:

[0048] Interlock control: automatically cuts off the burner power supply when the water level is too low; closes the water inlet valve and alarms when the water level is too high; water shortage protection: stops the furnace when the water level is below the minimum limit to prevent dry burning; leakage protection: the leakage circuit breaker instantly cuts off the power supply; overpressure protection: the safety valve releases steam to avoid excessive pressure.

[0049] The working principle and use process of the present invention are as follows: the water in the boiler body 1 drives the empty slot plate 24 to move up and down. When the empty slot plate 24 moves passively, it will slide within the T-shaped slide 22 through the connected T-shaped slide plate 23. Therefore, when the empty slot plate 24 moves and drives the buoyant water plate 27 to contact the water level plate 21, the fluctuation of the water body and the rise of the water body will cause the buoyant water plate 27 to be forced to squeeze the bellows 28, so that squeezing gas is generated inside. At the same time, the elastic telescopic member 26 installed between the buoyant water plate 27 and the empty slot plate 24 will also be forced to retract the rod body, and then the gas will be squeezed out of the bellows 28. The generated gas will enter the hollow sentinel body 230 through the special-shaped air pipe 29. When the airflow enters the cavity from the gap between the hollow sentinel body 230 and the reed 231, it encounters the trapezoidal air groove 232 provided on the hollow sentinel body 230. The 45-degree slope at one end of the trapezoidal air groove 232 will split the airflow into two streams, thereby generating a sound. The gas entering the cavity of the hollow sentinel body 230 will vibrate through the air and thus produce an effect of amplifying the sound. In other words, the sound emitted by the hollow sentinel body 230 can be used to alert the staff to pay attention to the boiler water level gauge and make corresponding work decisions such as shutting down the water pump to store water.

[0050] When the water in the boiler body 1 gradually decreases, causing the buoyancy water plate 27 to contact a group of water level plates 21 below, the triangular plate 234 installed on the outer wall of the empty slot plate 24 will first contact the top of the plate rod 235, and as the triangular plate 234 gradually moves downward, the plate rod 235 is driven to move according to the inclined surface of one end of the triangular plate 234, thereby squeezing the spring 238 in the rectangular slot 237 to cause it to deform. The installation of the spring 238 is convenient for the subsequent triangular plate 234 to gradually separate from the plate rod 235, driving the plate rod 235 to reset, and at the same time, the translation of the plate rod 235 will drive the L-shaped The ball rod 236 translates in real time, thereby touching the side wall of the arc-angle baffle 239, causing it to be subjected to force and rotated together with the vertical shaft 240 on the water supply pipe 11. The rotation of the vertical shaft 240 will drive the torsion spring 242 in the cylindrical groove 241 to be wound and deformed. The arc-angle baffle 239 that is driven to tilt 90 degrees can facilitate the operation of water storage in the boiler body 1. The staff only needs to hear the sound made by the buoyancy water plate 27 contacting the water level plate 21, notice the boiler water level gauge, and start the water pump in the existing technical device to store water. As a result, the operating cost is greatly reduced, and subsequent maintenance is convenient.
